Killing Floor by Lee Child

A little town in Georgia, Margrave. A man who has just arrived is arrested for murder.

He can't have committed it, as he wasn't in there at the time of the crime. But as a former military detective, he gets involved in the enquiry.

And in this incredibly rich town, where everybody seems well off, where the streets are too clean to be real, there are secrets he is going to understand and more murders happening, he's going to solve the mysteries.

But it will be at the price of many killed and tortured, including his own brother.

Once you've started it, you can't stop reading it.

The first appearance of Jack Reacher.
